My first image of the evening. Mars at 20h05 UT. Temperature outside -2 Celsius / 30 degrees Fahrenheit. Fortunately the frames for this picture of Mars were captured while I was sitting inside (5 meters away) wrapped in blankets and jackets and with a cup of coffee in the hand. I have extension cables connecting my PC to the telescope so I only work remotely.

My second image of the evening. Mars at 20h31 UT.

The black dots with the rings around them are dust donuts. Dust donuts are formed by grains of dust on my webcam's infrared filter. It casts a shadow on the webcam ccd detector. The shape of this shadow is an out-of-focus negative image of the main mirror or lens of the telecope. This shadow also contains an 'image' of the central obstruction/secondary mirror of my telescope.

From left to right:

• 170 best frames stacked in K3 CCD Tools
• Best frame (out of 1500) as determined by K3 CCD Tools
• Best frame made a little bit brighter to show its detail, lack of detail and noise

The processed result is shown below:

From left to right:

• 170 stacked frames with a little bit of sharpening
• 170 stacked frames with a more sharpening
• 170 stacked frames with maximum sharpening - to show maximum detail

The botttom row of pictures on this page were spaced 1 pixel between the first and second picture and 4 pixels between the second and third picture. This now looks evenly spaced.

Please let me know how your monitor displays these spacings. I would like to determine if I should trust the 1 pixel spacings even if it does look wrong on my monitor.

Thank you.
